RECIPE INGREDIENTS:
6 tablespoons butter
1 medium onion, chopped
3 tablespoons flour
2 teaspoons salt
1 teaspoon pepper
6 cups chicken broth
1 1/2 pounds mushrooms, sliced
3/4 cup sliced celery
3/4 cup chopped carrots
2 cups quartered baby red potatoes
1 cup chopped yellow squash
1 1/2 cups frozen corn kernels, thawed
2 teaspoons thyme
2 cups light cream
3/4 cup grated Parmesan, plus more for garnish if desired
2 cups chopped cooked chicken
1. In a large pot, melt the butter over medium heat. Add the onion and sauté until tender, about 6 minutes. Stir in the flour, salt, and pepper and mix until smooth. Gradually add the broth, then turn the heat up to medium-high and bring the soup to a boil. Add the mushrooms, celery, carrots, potatoes, squash, corn, and thyme. Reduce the heat and simmer the soup, covered, until the vegetables are tender, about 30 minutes.
2. Add the cream, Parmesan, and chicken. Heat the soup for an additional 10 minutes, but do not let it boil.
3. To serve, ladle the soup into a bowl and sprinkle it with more Parmesan, if desired. Makes about 15 cups.
I serve this with shredded lettuce, tomatoes, salsa, and sour cream. Whatever you usually put on a taco works. When I am feeding adults and don't have picky children that cry about sour cream, I take the sour cream and put it in a tube with a fluted end, and squeeze a pretty dollop onto each section of the cresent so it has little white "flowers" all around the ring.
But since I had lots of picky crying children tonight, I made it extra plain and we just added what we wanted afterwards.
